Prompting device for preventing vehicle from colliding with non-motor vehicles when turning corners and prompting method thereof

Abstract

The invention discloses a prompting device for preventing a vehicle from colliding with non-motor vehicles when turning corners and a prompting method thereof. A steering wheel turning angle sensor and a vehicle speed sensor are used to monitor the motion state of the vehicle in real time, and when the steering wheel turning angle is greater than a certain value, the vehicle is about to turn a corner to a greater degree. Two laser radars are simultaneously used to monitor the left back side area and the right back side area of the own vehicle, and then data of the laser radars are sent to a microprocessor. The microprocessor is used for collecting the data in real time, simultaneously judging the data of the laser radars, identifying the non-motor vehicles existing in the area behind the own vehicle and judging the dangerousness that the own vehicle collides with the non-motor vehicles in real time. The prompting device and the prompting method thereof require low investment costs and are suitable for popularized and used in large scale; and the prompting method of the prompting device has the characteristics of intellectualization and automation, a driver does not need to conduct any operation and the work reliability is high.

Description

technical field [0001] The invention relates to the field of safe driving of vehicles, in particular to a prompting device and method for preventing a vehicle from colliding with a non-motor vehicle when turning. Background technique [0002] Vehicles need to change their driving paths when driving to various forks on the road. This turning process is usually accompanied by traffic conflicts with non-motorized vehicles. The reason is that non-motorized lanes in my country are usually adjacent to motorized lanes. It is usually necessary to cross the non-motor vehicle lane, so it is easy to have traffic conflicts with non-motor vehicles. Typically, there is a fork with a green isolation belt between the motor vehicle lane and the non-motor vehicle lane. When the vehicle turns right, the driver's line of sight is disturbed, so it is impossible to observe the running state of the rear non-motor vehicle at the beginning of the turn. If there is a non-motorized vehicle running fas...

Problems solved by technology

Analyzing the structural characteristics of the vehicle shows that the driver's observation area behind the vehicle through the rearview mirror is easily disturbed by other factors, especially when the vehicle turns to a large extent, the reflection area of ​​the rearview mirror is closely related to the area that the driver needs to observe carefully. The areas do not match, so there is a greater security risk

[0003] At present, some technicians have proposed to use a method based on wireless communication to remind drivers to pay attention to the driving of non-motor vehicles. This method can detect other vehicles driving around the motor vehicle, but it needs to Corresponding radio transmitters are installed, this method has the characteristics of difficult promotion, especially for non-motor vehicles

At the same time, the early warning method based on wireless communication cannot accurately perceive the relative positional relationship and relative motion relationship between motor vehicles and non-motor vehicles
